对前置胎盘和胎盘早剥进行早期诊断与及时处理,是降低母儿死亡率的关键措施。B超检查可及时发现胎盘异常,图像清晰,出结果快,且无损伤。因而,B超检查可作为诊断前置胎盘和胎盘早剥首选方法。 资料与方法 采用我院因怀疑胎盘异常而进行B超检查的59例住院病人。使用ALOKa,SSD-210型及ALOKa,XD-256型探头,频率为3.5 MHz。 病人适当充盈膀胱,仰卧或侧卧位。用耦合剂涂抹腹部,在子宫部进行纵横和斜向扫查,仔细观察胎盘附着处与宫颈内口的关系。胎盘下界显示不清,可将先露部向上推移。若怀疑胎盘早剥应注意胎盘与子宫壁之间是否有异常回声。
The early diagnosis and prompt treatment of placenta previa and placental abruption are the key measures to reduce maternal and infant mortality. B-ultrasound can detect placental abnormalities in time, clear images, fast results, and no damage. Thus, B-ultrasound can be used as a diagnosis of placenta previa and placental abruption preferred method. Materials and Methods 59 inpatients who underwent B-mode ultrasound examination in our hospital due to suspected placental abnormalities. Use ALOKa, SSD-210 and ALOKa, XD-256 probes at 3.5 MHz. The patient is adequately filled with bladder, supine or lateral position. Abdomen with a coupling agent smear, in the uterine part of the vertical and horizontal scanning and oblique, carefully observed the relationship between placental attachment and the mouth of the cervix. Lower placental display is unclear, the first dew can be pushed up. If suspected placental abruption should pay attention to whether there is abnormal echo between placenta and uterine wall.
